`swam) J. scmFFxo, or OAKLAND, CALIFORNIA, AssmNoR or ONE-THIRD 'ro FRANK FRANZEN VAN D ON-'LHIIEID'10` LUCILLE PROTECTIVE `Applicatimr filed. September This iinvention relates to protective `apparatus, and is particularlydesigned forthe .protection of banks,;stores, treasuries orl `the rlike, when a hold-up is attemptedon such places.

The invention contemplatesa door whic mayclose the entrancefto a ',bank, v`for example, and'mechanism for closing .the door. The mentioned mechanism is `preferably actuatedby .an authorized (person at some distancefrom themechanism which operates the door. t

The invention 'further contemplates appa- .,ratus whereby one oiymore signals maybe .actuated when the ,door` operating `mechanism vis. put `into operation.

Another feature of the invention isthe `provision of meansfor locking the doonand .means for ,unlocking Athe same,v the unlock- `ing means being inaccessible .toa person unauthorized .to operate the `unlockingmechanism. 1 o

Other features and objects will be appar- .ent from .thefollowing specification.

The invention is illustrated inu the drawwings, iniwhich Figu-re1is,a perspective vewof part of 1a room fromthe 1interiorthereof, this` room being, for.example, afbanking room.

Referring to the drawings for more detailed description, the numeral 12 indicates a door opening from the street into a vestibule 13. Entrance from the vestibule 13 into the room 14 may be had through the doorway 15.. From the top of the doorway 15 is suspended a curtain 16 comprising chains 17 at the bottom of which is secured a bar`18 shown in Figure 8, and having eyes 4ure 7.

Vmovable collapsible door-25is located. `The Anear the ends. end thereof `a memberl, the .function of srod `28 is slidable yon the vertical rods 21 `and then pass' downwardly and are secured `44 andj45 to njlembers 46 and 47 which arc 1111.1.,130'1'11` or oAKLANm cainrromam.`

The bar 18 isslidable on the vertical rods 21, and since the' curtain 16 is made up mostly of a eeriesof 65 `vertical chains, Vthe curtain may be col- `lapsed when the door 25 ispushed upwards as may `sometimes occur as hereinafter" explained. Below thecurtain 16 a vertically 7() door `25 comprises an upper member 26 extending between the inner sides 23 of the `doorway l5. To the underside of the memv ber 26 is secured ay rod 28 shown in Figure The rod 28 has eyelets 29 at the ends thereof and apertured guide membersl()` i The rod 28 also. has "at one whi'chwill hereinafter .be explained. rllhe which .passythrough theinembers 30 of the p rod L28.

A .series of 'chains 33 are secured to `the .bar 28. ThesechainsfjmakeQthe door colylapsible Thedooralso comprises horizontal bars 35, 36 and 37. To the eyelets 29 ofthe bar 28 aresecured chains or cables 39 which extend upwardly and pass overpulleys`4() to members V411turnable with shaft 42 which is coupled at one end to an electric motor 43 shown, in Figure 1, as positioned alongside one end of the vestibule. 'lhe lower end of the collapsible door is secured as shown at raised above the floor 48 and constitute the bottom of the doorway. Uien the motor is actuated, it turns the shaft 42 on which ratchets 49 are secured. As the shaft 42 is rotated, the chains or cables 39 are wound 100 around the members 41, best shown in Figure 4, and such action raises the bar 28 and the door attached thereto since the cables 39 arc secured to the` eyelets 29 of the bar 28. As the shaft 42 rotates, pivoted dogs 50 engage 105 the ratchet-.s 49 and thus prevent the door from falling down. When the door is fully raised, the top of it is in contact with the bottom of the chain curtain 16. As the top of the door reaches its uppermost position,

which is just under the bar 18 of the curtain 16, the member 31, which isA positioned at one end of the bar 18 and best shown in Figure 3, moves a pivot switch and opens the circuit of the motor 43. As stated the dogs lock the door by engagement with the ratchet wheels 4.9.

Apparatus is provided to unlock the door and such apparatus comprises al cable 53 secured to the dogs at points The cable 53 passes upwardly and over sheaves 55 to a point 56 outside ot the building. The position 56 is so high that it may not be reached without a ladder or similar means. By pulling outwardly on the cable at the point 56, the dogs 50 may be made to disengage the ratchet wheels 49 and thus unlock the door. When the door isunlocked, it will fall and collapse ot its own weight until the member 26 falls within the members 46 and 47 and rests on projections 58 and 59 of the members 46 and 47 respectively, as shown in Figure i2. The chains 33 ot' the door 9.5 will then lie in colla pfied position between the members 46 and 17. In order to close the motor circuit opened by the pivot switch 52, the cable 61 is secured to the switch 52 and extends outwardly to a point 63 adjacent the point 56 on the outside of the building.

Referring now to figure 10, the numeral 65 indicates an annunciator which may be placed in any desired location. Numeral 66 indica-tes an electrically operated hell which is preferably placed on the outside of the building in order to give an alarm, and the numeral 67 indicates a lamp which is part of the alarm. The numeral 68 indicates a battery for operating the annunciator, bell and lamp. The numerals 69, 7 0 and 71 designate switches which, in case the apparatus of this invention is installed in a bank, may be in tellers cages. A line 72 leads from. a source of power to one terminal of the motor 43,

` the other terminal of which is connected by wire 73 to the lower terminal of the switch 69. Tires 7 el and 75 lead olf from the wire or conductor 7 8 to the lower terminals ot' the switches 70 and 71 respectively. The lower terminals of the switches 69, 76 and 71 are connected by means oil a conductor 76 to one terminal of therbattcry 68. The upper ter minals o't the switches 69, 70 and 7l are connected by means of a conductor 77 to' the other terminal ot the source ot power which operate-s the motor. The upper terminals of the switches 69, 70 and 7l are connected respectively by conductors 78, 79 and 8() with the annunciator 65. A condui'ftor 81 connects the annunciator 65 with the bell. 66. A conductor 82 connects the bell V66 with the lamp 67 and a conductor 83 connects the lamp with the battery 68.

l/Vhen an attempt is made to hold-up a teller in order to obtain money from him, the teller may close the switch as, for ex ample, the switch 69 which is within his cage and which may be adapted to be operated by the foot of the teller. The closing of the switch 69 closes the power .circuitso that the motor is actuated and the shaft 42 is rotated, whereupon the door is raised thus closing the exit and preventing the es- A cape of the person who attempts to hold-up the teller.

.From the diagram in Figure 10, it will also be seen that the closing of the switch 69 closes the alarm circuit so that the an` nunciator 65, the bell 66 and the lamp 67 are actuated.

I cla-im: l

In a device of the type described, a door frame having a. recess at the bottom thereof for receiving a. collapsible door, a cover for the top of said' recess which normally toi-ms the door sill, a collapsible door connected to said door sill, means for raising said door sill for causing said door to close the door opening, said means including a shaft mounted in said recess, a ratchet carried by said shaft and a pawl for engaging with said ratchet, said collapsible door being formed of chains that are shaped in a Y at the lower end thereof and secured to the sides of the walls forming the recess whereby the actuating mechanism disposed within said recess is protected.
